It's a Dell Optiplex 760 (refurbished). I don't remember the details but FreeBSD supports booting just fine if I dedicate all the HD to FreeBSD/GPT, but the Windows bootloader wont so I needed a bootloader with it's own EFI implementation that would. Clover comes from the Apple/Darwin world and does this but I never managed to install it in a HD; ideally you have to figure out how to install it before installing the OS so I had to install it later in a thumbdrive. FWIW, the only documentation I could find on the gory details for dual booting (with linux) is here: https://www.rodsbooks.com/gdisk/bios.html Cheers, Pedro.
